journal_commit_transaction() is 720 lines long. This patch pulls about 55 of them out into their own function, removes a goto and cleans up the control flow a little. Signed-off-by:

during truncate ext3 calls journal_forget() for freed blocks, but before these blocks go to the transaction and jbd reserves space in log for them (->t_outstanding_credits). also, journal_forget() removes these blocks from the transaction, but doesn't correct log space reservation. for example, removal of 500MB file reserves 136 blocks, but only 10 blocks go to the log. a commit is expensive and correct reservation allows us to avoid needless commits. here is the patch. tested on UP.

fix against credits leak in journal_release_buffer() The idea is to charge a buffer in journal_dirty_metadata(), not in journal_get_*_access()). Each buffer has flag call journal_dirty_metadata() sets on the buffer. Signed-off-by:

This removes as far as possible unneccessary vc_cons lookups by using a pointer to the vc_data structure instead of the index. The hidden currcons argument in console_macros.h is temporarily replaced with a hidden vc pointer. Signed-off-by:

With Frank Pavlic <pavlic@de.ibm.com> qeth network driver changes: - Using layer 2 mode IPv6 multicast addresses has not been registered at the OSA card (??? FIXME) - We have to allow QETH_IP_THREAD in qeth_set_online too when running in layer 2 mode otherwise multicast addresses won't be registered at the OSA card. - fake_ll improvements for dhcpcd. - Strip ethernet header of VLAN packets before calling skb_pull. This fixes multicast VLAN traffic stalls. - Fix unused variable warning. Signed-off-by:

Common i/o layer changes: - If a device driver tries to start I/O while the common I/O layer wants to start path verification, don't reject the I/O with -EBUSY (which might prompt the driver to retry the next tick) but seemingly accept the I/O and deliver a fake irb with deferred cc 1 after path verification has finished (prompting the driver to retry the I/O). This prevents the device driver from doing useless retries while cio is still busy with path verification. Signed-off-by:

Common i/o layer changes: - Update scsw information before checking activity control bits in the offline processing. - Clear irb structure after cio initiated I/O completed. - Modify cdev private structure only while holding the lock. - Update scsw information before checking whether we can start path verification. - Only generate a notoper event if the device is not already in the not operation state, otherwise we end up with two unregister calls.

On i386, SOFTWARE_SUSPEND requires the CPU to have PSE support, but DEBUG_PAGEALLOC disables PSE. Thus, allowing both options to be enabled simultaneously makes no sense. This patch disables DEBUG_PAGEALLOC if SOFTWARE_SUSPEND is enabled; it also displays a comment to briefly explain why DEBUG_PAGEALLOC is missing in that case. I have tested this patch against oldconfig and menuconfig on 2.6.11-bk2. Signed-off-by:

There are several cases where __init function pointers are stored in a general purpose struct. For example, a SCSI template may contain a __init detect function. Have not yet thought of an elegant way to avoid this. One such case is the mtrr code, where struct mtrr_ops has an init field pointing at __init functions. Unless I overlook something, this case may be easy to settle, since the .init field is never used. The patch below comments out the declaration and initialisation of the .init field of struct mtrr_ops, and puts #if 0 ... #endif around the centaur_mcr_init() and cyrix_arr_init() code. Simultaneously a number of variables are made static. Signed-off-by:

Because Xen is compiled with -Wall -Werror, has inherited processor.h from Linux and Fedora is now built with gcc4, I discovered this bug. The few callers I verified all call cpuid with unsigned ints, but the function is defined with signed ints. This trivial patch fixes that. Signed-off-by:

When CONFIG_HIGHMEM=y, but ZONE_NORMAL isn't quite full, there is, of course, no actual memory at *high_memory. This isn't a problem with normal virt<->phys translations because it's never dereferenced, but CONFIG_NONLINEAR is a bit more finicky. So, don't do __va() in non-existent addresses. Signed-off-by:

Those CPU's are found mostly in embedded systems ... one of the most prominent Hardware using GEODE CPU is probably soekris net4801 (http://www.soekris.com). This patch has been on my homepage (http://www.sk-tech.net/support/soekris.html) for quite a time - but I've been asked several time to have it included in the main kernel. Signed-off-by:

ioremap() has special-case handling for the IS region, but inunmap() does not. So iounmap() generates a warning when a caller correctly performs an ioremap()/iounmap() sequence. Fix that by teaching iounmap() about the IS address range. Signed-off-by:

The current SCx200 drivers use a fixed base address of 0x9000 for the Configuration Block, but some systems (at least the Soekris net4801) uses a base address of 0x6000. This patch first tries the fixed address then - if no configuration block could be found - tries the address written to the Configuration Block Address Scratchpad register by the BIOS. Signed-off-by:

in arch/i386/mm/init.c, there's a #define for __free_all_bootmem(): #ifndef CONFIG_DISCONTIGMEM #define __free_all_bootmem() free_all_bootmem() #else #define __free_all_bootmem() free_all_bootmem_node(NODE_DATA(0)) #endif /* !CONFIG_DISCONTIGMEM */ However, both of those functions end up eventually calling the same thing: free_all_bootmem_core(NODE_DATA(0)) This might have once been a placeholder for a more complex bootmem init call, but that never happened. So, kill off the DISCONTIG version, and just call free_all_bootmem() directly in both cases. Signed-off-by:

discontig.c has its own version of set_max_mapnr_init(). However, all that it really does differently from the mm/init.c version is skip setting max_mapnr (which doesn't exist because there's no mem_map[]). Signed-off-by:

Refactor the i386 default and CONFIG_DISCONTIG_MEM setup_memory() functions to share the common bootmem initialisation code. This code is intended to be identical, but there are currently some fixes applied to one and not the other. This patch extracts this common initialisation code. Signed-off-by:

Dave Hanson mentioned I should send this patch to you. I posted it to linux-mm a while ago without complaint. This patch solves a simple problem related to the interpretation on the SRAT table and the info found in the e820. When a possible hot-add area is exposed on my box (IBM x445 with hot add enabled in the bios) my SRAT table correctly exposed a new node from the end of my physical memory to 64gb. In the present kernels the numa KVA areas (based on the SRAT) are calculated before find_max_pfn. The remap area is created for this large non-populated zone and the system dies a while later during bootup. I believe the correct things to do (as did the hot-plug community) the correct thing to do is the keep the node_start_end_pfn data structures focuses on memory that is in the system. That is all this patch does. It ignores any node data (correctly reported by the SRAT) that is above the e820 end of memory. Signed-off-by: <kmannth@us.ibm.com> Signed-off-by:
